A faster HRR after exercise indicates greater cardiovascular fitness.

A faster HRR after exercise indicates greater cardiovascular fitness.

• A. Lower fitness
• B. Greater cardiovascular fitness
• C. No relation
• D. Higher resting HR

Answer: (B)

Heart rate recovery after stopping exercise shows how quickly the heart returns toward resting levels, driven by how rapidly the autonomic nervous system reactivates the parasympathetic (vagal) influence. In people who are more fit, parasympathetic reactivation happens sooner, so the heart rate drops faster. That quicker drop indicates greater cardiovascular fitness. The other possibilities don’t fit because slower HRR is associated with lower fitness, there is a clear relationship between HRR and fitness, and HRR specifically measures the rate of decline after exercise rather than the resting heart rate itself.
